Virus Serology. Blood samples will be collected for testing for hepatitis B and hepatitis C as indicated in Table 3. If the initial hepatitis C result is positive, then the patient will need to return for an unscheduled HCV RNA assessment to determine if the virus is present at the current time. If the results of this test are negative, the patient may continue in the Screening process.
Virus Serology. Subjects will be screened for hepatitis (HBsAg and anti-HCV) and HIV prior to being enrolled in the study. If subjects are positive for anti-HCV, reflex RNA testing (viral load) for HCV should be conducted; those subjects with positive anti-HCV may be enrolled only if the viral load is negative.
